Definitions

  • the present invention is directed to a pulsator and a washing machine having a pulsator that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
  • a lower portion of the tub may include a bottom surface to accommodate a lower portion of the lower pulsator.
  • Figure 3 illustrates an exploded perspective view of the pulsator shown in Figure 2 ;
  • the lower pulsator 200 may be coupled to the upper pulsator 100 and fixed to a driving shaft that is rotatable in forward and reverse directions by means of a motor. Accordingly, the lower pulsator 200 may be rotated in forward and reverse directions by the driving shaft. As will be described with greater detail below, the lower pulsator 200 may further include a plurality of lower washing ribs 210, a guidance surface 220, and an outlet 240.
  • the outlet 240 may be provided at the end of the guidance surface 220 and enable the flow passage 250 to communicate with the lower surface of the lower pulsator 200. Accordingly, water introduced through inlet 120 may be channeled by and flow downwardly through the flow passage 250 and be discharged under the lower pulsator 200. In one aspect of the present invention, the outlet 240 may be arranged along the circumferential edge of the guidance surface 220.
  • the upper and lower pulsators 100 and 200 may be coupled together to form a pulsator assembly 400.
  • the upper and lower pulsators 100 and 200, respectively, of the pulsator assembly 400 should be substantially inseparable when used in a washing machine. Accordingly, an edge (e.g., a circumferential edge) of the upper pulsator 100 may be bent to enclose a corresponding edge (e.g., a circumferential edge) of the lower pulsator 200, thereby fixing the upper pulsator 100 to the lower pulsator 200.
  • the surface area increases compared with pulsators of the related art. Moreover, when an external force substantially equal to that of the related art is applied, the stress per unit area of the upper pulsator 100 decreases and the structural rigidity of the upper pulsator 100 is maintained.
  • grooves 270 are provided in the upper surface of the lower washing ribs 210 adjacent the center of the lower pulsator 200, at regions corresponding to location of grooves 170 in the upper pulsator 100.
  • the grooves 270 of the lower pulsator 200 conform substantially with the grooves 170 of the upper pulsator 100.
